If you have opened a Google document, spreadsheet, or presentation in a web browser on your mobile device in the past week, you may have noticed that Google is rolling out a new look.

The updated interface is simpler, and the changes are consistent across all three services. An action bar stretches across the top that lets you go back or start editing. The title of the document sits in the center. In most cases the bar is gray, but it turns dark when viewing slides.

Google is taking this time to phase out the ability to edit Docs files on the web.

We detailed a new YouTube interface back in March that stripped the app of its hamburger menu and replaced it entirely with tabs. Now the look seems to have rolled out to a wider number of users. A ton of you have reached out to us with the news, and at least one of us at Android Police has received it as well.

Here you can see the new interface with the four primary tabs—Home, Trending, Subscriptions, and Your Profile—spread across the top.

The share button inside YouTube is unlike the icon used in virtually every other Android app. Rather than the usual set of three connected dots, we see a horizontally flipped version of the reply symbol in Gmail. Well, Google isn't yet changing the iconography, but it does seem to be testing out a new location.

In addition to the share button's usual home at the top-right corner of a video, we're also seeing it next to the like and dislike buttons.

If you're not seeing the new layout, try closing the YouTube app and opening it again. That works for some users.

WordPress went material in version 3.5. Now in 4.1, the app has undergone what may be an even larger design change. Say goodbye to the navigation menu you're used to sliding out from the side of the screen. Now everything you need is tucked away inside four tabs spread along the action bar at the top.

The first tab, which also serves as the landing screen, provides just about everything you'd expect in the side menu. From here you can view your site and open posts. When you click the back button, it takes you back to this page.

Remember that "Voice Access" talk that was supposed to happen at I/O but was removed from the schedule? It turns out that, while it wasn't the full-on in-app voice craziness we had hoped for, Google did have some news about voice interactions to share.

Specifically, with Android M, Google has introduced the Voice Interaction API, which will allow apps to get a better handle on a user's voice-initiated requests. Check out the video below, by the leaders of a sandbox talk at I/O about voice actions.

The new interface looks quite a bit like the Android app. You have one panel with contacts, messages, and calls on the left, and the active conversation thread is visible to the right. A floating action button lets you open up a new conversation.

For the most part, Ultraviolet currently resembles the Android app - it's got green toolbars, and a one-at-a-time approach to viewing conversations or the conversation list. Plus on OS X, the floating buttons unfortunately still aren't transparent, so the whole app is wrapped up in a window.

According to Caschy's Blog though, Google might be testing a new interface for Ultraviolet, and the image posted there looks like a step in the right direction.

As our internal collaboration platform, Hipchat is special to the AP team. It's a great service for keeping track of assignments, chatting with team members, and sharing info, but until now the mobile app has been just a little behind the curve on design.

Today it looks like that's changing, as Hipchat beta received an update with material design.

The new Hipchat beta has native rendering for messages and will now honor your system's font size settings, but of course the overarching design is the real story here. Here's a look:

The "lobby" has been transformed into a "chats" screen, with people and rooms in the same view.
